[Openocd-development] [PATCH] Add support for the DLP-USB1232H JTAG module

Hi,

I recently got a DLP Design DLP-USB1232H UART/SPI/JTAG module which is
based on an FT2232H chip. I originally intended to use it to flash SPI
BIOS chips from various mainboards (for details on that setup see
http://www.coreboot.org/Flashrom/FT2232SPI_Programmer).

However, this module is equally well usable as JTAG programmer if
connected to the JTAG target properly. I have successfully wired the
module to an Olimex STM32-H103 eval board and flashed a firmware onto
that using OpenOCD using the interface config file attached.

The nice thing is that everything worked pretty much out of the box, I
didn't have to change a single line of code in the OpenOCD source.

I documented the details at:
http://randomprojects.org/wiki/DLP-USB1232H_and_OpenOCD_based_JTAG_adapter

The attached patch adds the respective config file to OpenOCD.


Thanks, Uwe.
